Before launching the satellite & space shuttle it is the most important test. I am writing the article for the sake of budding youngsters. Without doing the vibration if satellites are launched all the components or parts will break up & comeout of the capsule. The world runs on mechanical vibrations. Even a quartz clock runs on vibrations when an electric current pass through the piezo electric crystal, crystal vibrates. This is the principle of quartz clock. Vibration is strong phenomenon on earth. When PSLV lifts off the spacecraft or satellite carried by PSLV experiences 15g condition (‘g’stands for acceleration due to gravity). The condition of accelertion due to gravity is tested by accelerometer. 120 accelerometer are placed near the instrument of space shuttle & satellite so that each part could be tested. If a part or component gets cracked by the vibration while testing they will replace the part & component.

Chandrayan Of India
Although Moon was explored in the 1969 by the Americans it is very much less we learnt about the Moon. Moon is a very mysterious place for scientists. It is Indians turn to explore the moon. Indians are launching polar satellite launch vehicle into the orbit. Polar orbit is 800 to 1500 kms from the earth. Indians are launching unmanned mission into the PSLV orbit. launching depends on the exact positioning of the earth sun & the moon. Indians wants to explore the poles of the moon. Polar region of the moon is a mysterious place of atmosphere. Helium gas & gravitational forces need to be studied properly. The space craft is tested on space simulator.
1) Vibration test – before launching the space craft to the moon vibration test carried out on spacecraft. Space shuttle should with stand the 16 tonnes of vibration.
2) Space shuttle should tolerate a noise similar to noise produced by 10 jet engines.
3) Temperature test – It should withstand the temperature of 100′c
Space shuttle should map systematically topography of the moon and chemical 7 micrological mapping of moon to understand the process of formulation & chemical evolution of moon.

Neutrino Observatory
Neutrino are the smallest particles of neutron which is a neutral charged particle of an atom.Stars are emitting continuosly millions of neutrino particles per second. It will pierce through the earth and even human body. It is impossible to capture the nuetrino in the atmosphere because there are other particles of light. We need dark tunnel to capture the nuetrino particles. Americans are trying to capture it in Ohio salt mines and Italians are trying to capture it at worlds Biggest tunnel. Japanese are also trying to capture in the mines. Other countries are trying to capture the neutrino particles on water or ice or on the salt. Our country is piling up Iron of 1 Lakh tonnes in the tunnel. The density and Volume of Iron is high. So it is easy to capture Neutrino particles. There is more possibility of capturing nuetrino particles. Although we failed to capture neutrino particles in teh Kolar Gold field 30 years back. I hope we will be succesful this time. As a kid & as a child prodigy I spoke about this with lot of people but they fail to understand. Now I hope people also understand this. When I was in the 6th & 7th grade our country failed to capture the neutrino particle & I hope we will be successful at my age of 42 years.

Space Junk
After the launch of Sputnik by Russia, dozens of countrie launched satellites. There are around 500 satellites now in space. After their expiry, they become junk in space. This simply revolves in space. I feel it is better to bring this junk from space.
The consortium of countries should build the space shuttle capable of bringing the junk from space. It may take another 5 to 8 years to build it. Russia which has experience in building MIR space station, ISS can take a lead in this.
My imagination of Crab shuttle, which is a rocket having a crab like structure is sent to space. It opens up its crab like structure then picks up the satellites & putting into its capsule of rocket & brings back to earth. Crab like structure is having arms of crab like operators on computer control from earth. The algorithm given to crab like structure by calculating the motion of satellites. This is possible with the help of experienced scientists.
